Polis Annual Conference Madrid 28 November 2014 ZeEUS Stockholm Case Study Jonas Ericson SL Introduction by Stephanie Leonard UITP
Electromobility in Public Transport Electrification already produced a revolution in Public Transport X From horses-powered to electrical trams UITP was already following such trend: The high cost of horses maintenance vs. electricity traction was one of the key topics discussed at the UITP s Berlin Congress in 1886.

ZEEUS - Zero Emission Urban Bus Systems Evaluate the economic, environmental and societal feasibility of high capacity electric urban bus systems through demonstrations Provide decision makers with Guidelines and Tools to support decision on if how and when to introduce electric buses in the core bus network Facilitate the market uptake of urban electric buses 40 partners, 10 Countries, Coordinator: UITP Total budget: 22Meuro / EU funding 13.5 Meuro 42 Months (until March 2017) www.zeeus.eu 5
ZeEUS Demonstrations 8 Core Demonstration Barcelona, Bonn, Cagliari, Glasgow, London, Münster, Plzen, Stockholm ~35 electric buses 12 meters, articulated, doubledeckers Plug-in Hybrid, Full-electric, Battery Trolleys Energy supply modes: plug-in, conductive, inductive, overhead Fast and slow charging strategies Overnight (depot) Opportunity(terminals, bus-stops) Observed / Monitored Demos Core Demonstrations Observed Demo (first contacts) 50 contacts already! Annual publication & workshops UITP 6
ZeEUS - Guidelines and Tools to support Decision Makers on if, how and when introduce e-bus in cities ZeEUS Observatory Collect information about activities about e-buses worldwide Linked to UITP FTSO ZeEUS Observed and Monitored Demonstrations Yearly publication, workshops - data collection and evaluation Funding schemes, tools and procurement guidelines Interaction with European funding entities Update of UITP tender structure to include electric Buses Standardisation of electric buses ZeEUS/UITP Steering Group about standardisation of electric buses Harmonise EU activities on ebus standards UITP COMs, project partners, PT associations, Standardisation bodies... Link with EC Directive on Alternative Fuels Infrastructure E-SORT validation and tuning New chapter of UITP SORT cycle for full-electric buses Consolidation and validation of SORT-E through the project Demonstrations Coordination with the UITP SORT working group Strategy for optimised interaction with the power grid Optimised overnight charging strategy / business model Strategy for re-using existing PT power network for fast charging at bus-terminal / stop Regulatory frame Include operational aspects Guidelines for including electric buses in National Policy Framework definition ZeEUS Vision demystifying electric buses ZeEUS Electrification Roadmap research and implementation Implementation aspects Recommendations for urban / spatial planning Operational concepts Fleet migration scenarios Drivers and maintenance staff training Network with emobility activities Projects / Initiatives Urban mobility and energy stakeholders 7

Battery Bus 1984 Electric Hybrid 1996-00 Flywheel 1984 Multiflex 1993 Gas 1984 Biogas 2003- Accumulator 1989 Fuel Cell 2004-06 Ethanol, 1990-
Stockholm s Philosophy Use best available commercial technology NOW!! Support and engage in projects for future technology (hybrids, electric, fuel cell etc)
Distribution of bus technologies 2,100 buses 85 % renewable Biogas 14% Fossil Diesel 15% Ethanol 33% Biodiesel hybrid 2% Biodiesel RME & HVO 36%
The bus Volvo 7900 Plugin 4x2 12m Hybrid bus
2014-12-04 15 8 Plug-in electric hybrid buses full scale traffic conditions replacing existing buses on established route 6 min charging at end stations Electric drive approx. 7 km Geo-fencing Normal hybrid if no charging 85 % CO2 reduction w HVO Low noise, no exhaust emissions 60 % Energy saving
Technical objective demonstrate low emissions low energy consumption low noise level high performance and cost efficiency 16
2014-12-04 17 Buses by Volvo Hybrids with larger batteries + charging HVO (advanced biodiesel) for range extender Charging system by Vattenfall Fast charging at end stops Slow charging at depot Operation by Stockholm Transport Operation costs Depot adaption Evaluation

2014-12-04 23 Strategic issues What is needed for electrification? Balance batteries infrastructure? Who should finance, own, set up infrastructure? Authority? Operator? City? Where?
Charging infrastructure Two charging stations, end of the route 150 kw 1 km electric drive/min charging Transformer box approx.1,3x4,3x3 m Slow charging during night at depot
